Abstract
The Director's Composite Eyeglass performs a digital compositing function of two video images, using a blue screen key to matte the foreground image over the background. It is a chroma-key device implemented in digital hardware. There is a live video feed from which a frame can be captured into memory for use as a background image. This image is then composited with a foreground image, which is shot against a blue screen background. The device filters out the blue screen area from the live foreground image and replaces it with the underlying background image from the frame buffer. The Director's Composite Eyeglass uses modern, special and general purpose hardware to successfully implement this compositing function.
